Origin version 1.20.1-1.10.0.9

For some reason on my friend's world (hosted through Essentials), I cannot phase through blocks as a phantom. However, trying other unofficial origins with phasing does work. My other friends are also unable to phase as the phantom. Phantom mode still triggers, and you still burn in sunlight without it, so everything else works. I have also tried switching origins, rejoining the world, and restarting the game as a whole (my friend has also tried restarting the world). But nothing has worked.

I assumed it was a mod interaction at first, however phasing works as normal in single-player worlds, as well as other multiplayer worlds, so I'm left to assume that it's something in the world data that might've broken it.

I would love help and will provide a mod list if needed.
